' Application led Angnst1|9 1899. v Serial No. 727,754. (llo model.) i vTo @ZZ whom" 'it may 'concern' i Be it known that I, .ARTHUR KLEINRELDT,

acitizen of the United States, residing in Newv Yorlgborough 4ofManhattan, and' State of New York, have invented certain new and usefulImprovements in BeerSiphons, of which 'the following is ,aspecification.

This invention yrelates to'certain improve! 'ments `iii-beer sipho'ns'orvesselsl of that class in which are contained fermented liquids un-ld'era pressure ofl carbonio-acid gasand from which the liquid can bevdrawny through a' valvcd spout under pressure of the'gas until thevessel is entirely emptied. l vA number of,

devices have heretofore been proposedy for thisfpurpose, but so farwithlittle, practical success,partly for the reason thatthe vessels weretoo cumbrous and little adaptedfor vcfOnvenient refrigerationandpartlyfor the rea` 2o son that the mechanism by which the car#,bonita-acid gas was suppliedv from its receiver to the'liquid-containing'vesseldid `:not func- Wheninnse. i The object of thisinventionA is to supplya tion with'a suiiicient degree of reliabilityder pressnreof carbonio-acid gas whichhas and eiec'tive manner,so that asuflicient quantity of carbonio-acid gas is supplied for forcjingoutvall the liqud'contained in the vessel the same, anf'opening in' the'bottom of said. receiver, .a valv'for opening and closing said consistsof a beerfsiphon which comprise a under uniform pressure; andtheinventin carbonio-acid secured to the neck-of the vesopening,a diaphragmconnectedwith the stem of said' valve,achannel connecting. the spaceonthe pressure side of the diaphragm with a v fbor'e `in the neck of theVreceiver and with the i interior of the .liquid-containing vessel,openlings .for connecting the-space at the opposite side 'of .thediaphragm with 'the atmosphere,

Vand avalved siphon-tube for'drawingoi the liquid under pressure fromthe liquid-con- 'i taining vessel'.

The invention consists,furtl1er, of. certain details of construction,which ,willbefully described hereinafter, and iinallyfpointed out 'intheclaim. r

In the accompanying drawings, 'Figure 1 represents :aside elevationxofmy improved beer-Siphon. Fig. 2 is a vertical central secl tion-,throughthe1 head of the s iphou, drawn on alarger scale; vand Fig. .3 isa,bottom-view,

Similar letters. of reference indicate 'corre-4 sponding parts.

Referring tothe drawings, A represents a4 .vesselwhich ispreferably-made otglass in the general-shape ofail-ordinary s'iphon forcarbonated Waters, sai'dsiphon being made oli sufficient size tocontainfone, two, or more gallonsof fermented liquid, such as,beer,ale,Wine, &c.- The liquid vessel Aecan also be madeof steel or. other.suitable material,

though it is preferable .to 'make it offglass, soI fjthat'the contentsof 'the vessel canl be readily seen.' .The vessel A is providedwth-aneckci, having an interior threadgintofgwhich is tightly .screwed andcemented a" bushing b, into which the threaded neck/r of a'carboni'cacid receiver R is screwed. A ringshaped gasketjcl, of elastic-material,isinterposed be-- tween the shoulder r ofthe neck of 'thefre-l ceiver R:and' the recessed top part of the ,bushing b, so as tosecurethetightiitting of the receiver to thenec'k'of 'the liquidi vessel, ,Thecarbonio-acid 'receiverR is preferably made of copper.- or othersuitable material, its upper part being 'dome-shaped, while'its vloweredge is securely soldered or brazed into the upper half of adiaphragm^casingiD,-the lower Vhalf of 'which is secured :by s crewsb tothe upperhalf, said two halves holding the sheet-metal diaphragm Dtightly-imposition between their circumferential" rirns.-A 'The' neck rof the receiver-R isjcast'integral with the lower half of-the.diaphragm-'casting D, said lower half being provided with anumber'of-.openings d', so that atmospheric pressurejs exerted on the'under side of: the dia- Phmgill-D'f e l The; receiver 'R s provided vatits central top part with anl opening having au interiorly-threadedbushing e, into which is screwed a plug E, which has a centralperforation f, the inner end of which is closed by a springactuatedvalve ff, retained by a'perforated cage f2. The valvedplugE servesforcharging the receiver R with carbonio-acid 'gas under pressure'. Thecarbonio acid'is preferably supplied'to the receiver by connecting .theupper threaded end of'the plug Ewith -pre'ssure in the receiver fa tubeconnecting it with the outlet-valve of a cylinder lcontaining liluidcarboui'c acid. -As soon as the required 4 The stem g of the valve gpasses throughl the has been removed, and therebythe position' opening oand is connected with the center of 4the diaphragm D'.

The valve q is 'provided with an interiorly-threaded socket, so that itcan be adjusted higher or lower on the threadf 'ed upper end of thevalve-stem. The valve g' has' a nick gz in its head, so that ascrewdriver can be inserted through the opening in the 'top of thereceiver R after the' plug E of the valve g on its stem' adj ustedhigher'or lower relatively to its valve-seat. A' channel hin the-upperhalf' of the diaphragm-casiog'h D leads from the space above thediaphragm theower half of the casing D and then in an inclined directionin the same to a center bore h' in the neckr, as shown in Fig'. 2, S'oas to place the space above in communication with ythe interior of theliqvuid-containing vessel. The upper end of the bore h' isclosed byaspringactuated escapevalve h, sothat in case the pressure in theliquid-containing vessel should rise'above the required pressure theescape-,valve will be liftedagainst the tensionnh'tsspringand thesurplus gas 'discharged into the space below the diaphragm and fromthesame into the athere. -As soon as the normal pressure for which theescape-valve is set is established inthe liquid vessel the Aescape-valvewill close again the central bore of .the neck fr. The lower halfl ofthe valve-casing D is further providcd with an outlet -channel 'L' of Ylarger size than the channels'h h', said outlet-channel being providedat its inner -end with a nipple i, to which .a siphon-tube F is appliedby means of an elastic sleeve s, said sleeve permitting a certain playto the si phontube, so that during transportation or by egree ofpressure is provided with an opeu` ingo, having a beveled `valve-seato', on which rts tightly a correspondingly-shaped valve g.

the diaphragm give suiciently'so as to be prevented'from breaking. Theoutlet-channel is provided with an exteriorly-threaded nipple i* at itsouter end, to which a discharge-spout G, having avalve, faucet, o rother'suit'able device G', is applied. This discharge spout or nozzle Gis screwed onto the nipple of the outletchannel, which nipple ispreferably cast integral wth the lower half of the diaphragmcasing D.Anysnitable construction of valve or stop-cock for the discharge-spoutmay be used, that shown in the drawings being in the nature of anordinary lever-actuated valve, such as commonly used on siphonsforaerated waters.

The receiver R is provided at diametricallyopposite points of its sidewall with sockets for receiving the inwardly-bent ends of a pivoted bailB, by which the siphon can be conveniently carried.- When the bail isnot in use, it assumes an inclined position of rest, as shown in Fig. 1.The operation of my improved beer-siphon is as follows: The fermentedliquid is charged 'into the liquid-vessel A under pressu're'ot car-'bonic-acid gas through the discharge-spout in the same manner as thesiphons for aerated waters are charged, or the liquid is charged without-pressure into the liquid vessel by uuscrewing the neck of the receiverfrom the bushing in the top part of the vessel and then.

.supplying the vessel with the determined quantity of fermented liquid.The receiver is then screwed again into position in the bushing of thevessel. The plug E is then removed ,and then connection with a cylindercontaining liquid carbonic acid establshed.-

As soon as the required pressure of carbonio acid in the receiver isobtained, which is read off on a suitable pressure-gage connected withthe Asupply-pipe leading from the' cylinder to the receiver, 'the cap isplaced on the plug E and the receiver thereby tightly. closed. Duringthe charging of the receiver wi th carbonicacid gas the diaphragm is inits normal posi- -tion' with the valve g in open position-z'. e.,

vaway from its seat-so that the gas can pass through the opening or porto into the space above-the diaphragm and through the channel h h intothe spaceabove theliquid in the vessel A. 'As soon as the requiredpressure .is established in the receiver Rand the liquid-containingvessel A the back'pressure of the'gas from the liquid vessel will actupon the diaphragm D', so that it will bulge downward and close thevalve g tightly on its seat o', so as to Iinterrupt the connection ofthe liquid vessel with the receiver. ,The parts remain in this conditionuntil liquid is to be drawn from the vessel A by opening the valve ofthe discharge-spout. As soon as the discharge-spout is opened, theliquid will flow through the Siphon-tube and the spout into thereceptacle held below the same. The gas-pressure in the liquid vessel Aabove the liquid is reduced during the discharge of the liquid, andthereby ythe pressure on the diaphragm reduced, so that it will returninto its normal position and lift the valve g, Wherev by a new supply ofgas can pass from the receiver to the liquid vessel. As soon as thevalve of the discharge-spout is closed and the p outiiow .of liquidinterrupted, the back pressure ofthe gas in the liquidvessel will againact on the upper surface of the diaphragm and press the same downwardinto slightlybulged shape, so as to cause the valve to be seated firmlyon its seat and interrupt therevby the connection of the receiver withthe liquid vessel and the supply of gas to the latter. To secure'therequired pressure yin the liquid vessel, the valve is adjusted oniitsvalve-stem either in upward or downward direction. When the valve isadjusted higher on its stern, a greater pressure is necessary to closethe valve thanvlwhen the valve is adj usted lower on its stem, in whichcase -a smaller pressure isrequired.

My improved beer-Siphon has the advantages of compact shape, so as to beeasily cooled either in thez refrigerator or cooler. .All the parts bywhich the carbonio acid is supplied to the liquid vessel are fullyinclosed -and not liable tobe rendered inoperative. y The siphon can bemanufactured at compara- -tively-small expense and enables the consumerto be supplied with fermented liquids in larger quantities, such as oneor tvvoI or more gallons, in place of delivering them in bottles in theusual manner. As the liquid drawn from the siphon is always underpressure of carbonio-acid gas it is more refreshing and palatable andcan be drawn 0E at differenttimes and in any desired quantity, thesiphon being then returned to the refrigerator, so that its contents arekept cool and ready for use Whenever required.

Having thus described my invention, I 7

claim as new and desire to secure by Letters Patent- The combination,with a liquid vessel, of a carbonio-acid receiver provided with a necksecured into said liquid vessel, said neck having a longitudinal bore, adiaphragm-casing at lthe lower part of said receiver provided with anopening communicating with the atmosphere, a diaphragm supported by saidcasing, a valve located in the receiver, a stem connecting said valvethrough the opening or port in the bottom of the receiver with thediaphragm, a gas-supply channel connecting the space above the diaphragmwith the liquid vessel, a spring-actuated escape-valve at `the upper endof said bore, an outlet-channel located in the lower part of thediaphragm- Y casing, a Siphon-tube connected with the inner end of saidoutlet-channel, and a valved discharge-spout connected with the outerend of said outlet-channel, substantially as setl forth. i l q Intestimony that I claim the foregoing as my invention l have signed myname in presence of tWoV subscribing Witnesses.
